Why overlap memos fail without a shared verb list

When overlap discussions spiral, the missing ingredient is rarely math — it is language. Teams import different verbs for the same chart: "reach," "audience," "targetable," each carrying hidden assumptions.

We recommend a pre-read sheet that locks verbs for the meeting. Spend ten minutes agreeing on definitions, then show numbers. The discipline feels slow once, then saves hours weekly.

In KR cohorts we often see mixed English and Korean shorthand in decks. Pick one glossary for the quarter and stick to it, even if it feels formal.

Finally, document what you will not claim. Explicit non-goals keep exec readouts calmer than defensive footnotes.
